   Closes the current session. This method is automatically executed internally by PHP when
   closing the session, or explicitly via <span class="function"><a href="function.session-write-close.html" class="function">session_write_close()</a></span> (which
   first calls the <span class="function"><a href="sessionhandler.write.html" class="function">SessionHandler::write()</a></span>).
  </p>
  <p class="para">
   This method wraps the internal PHP save handler defined in the
   <a href="session.configuration.html#ini.session.save-handler" class="link">session.save_handler</a> ini setting that was set
   before this handler was activated by <span class="function"><a href="function.session-set-save-handler.html" class="function">session_set_save_handler()</a></span>.
  </p>
  <p class="para">
   If this class is extended by inheritiance, calling the parent <em><code class="parameter">close</code></em> method will invoke the
   wrapper for this method and therefor invoke the associated internal callback.  This allows the method to be
   overidden and or intercepted.
  </p>
  <p class="para">
   For more information on what this method is expected to do, please refer to the documentation at
   <span class="function"><a href="sessionhandlerinterface.close.html" class="function">SessionHandlerInterface::close()</a></span>.
